Code Compliance Flashcards

Under OSHA 29 CFR 1926.62, what is the permissible exposure limit (PEL) for airborne lead on construction coating removal projects?

Answer: 50 µg/m³ as an 8-hour TWA

The OSHA construction lead standard sets the PEL at 50 µg/m³ averaged over an 8-hour workday.

A blasting crew's lead exposure monitoring shows 35 µg/m³ (8-hr TWA). Which OSHA threshold has been exceeded?

Answer: The action level of 30 µg/m³

35 µg/m³ is above the 30 µg/m³ action level but below the 50 µg/m³ PEL, so action-level requirements such as monitoring and medical surveillance apply.

Under 29 CFR 1926.62, a worker must be medically removed from lead exposure when a blood lead level reaches or exceeds what value?

Answer: 50 µg/dL

The construction lead standard requires medical removal at 50 µg/dL, with return allowed once two tests show levels below 40 µg/dL.

Spent abrasive from lead paint removal is tested by TCLP. Above what leachate concentration of lead is the waste classified as hazardous (D008)?

Answer: 5.0 mg/L

The RCRA toxicity characteristic limit for lead is 5.0 mg/L in TCLP extract.

Which OSHA standard requires a written respiratory protection program, fit testing, and medical evaluation for respirator users?

Answer: 29 CFR 1910.134

29 CFR 1910.134 is the respiratory protection standard and is referenced for construction work.

Under OSHA Hazard Communication (29 CFR 1910.1200), how many sections must a Safety Data Sheet contain?

Answer: 16

GHS-aligned HazCom requires SDSs in a standardized 16-section format.

What type of respirator is typically required for an operator doing open abrasive blasting?

Answer: NIOSH-approved Type CE abrasive-blast supplied-air respirator

OSHA abrasive blasting rules require blast operators to wear abrasive-blasting respirators, which are NIOSH Type CE supplied-air units.
